Melt the chocolate in a heatproof bowl over a small pot of simmering water. Make sure that the bowl isn't touching the water, as this will cause the chocolate to burn.
While the chocolate is melting, mix together the remaining ingredients with a hand mixer on medium speed for 3 minutes. Ensure the mix is fully combined.
With the hand mixer on low speed, slowly add the chocolate mixture to the other ingredients. Mix on medium speed for 2 minutes.
Add the mixture to a piping bag and pipe the fat bomb mixture onto a lined tray. Set in the fridge for 40 minutes.
Whip the heavy cream and pipe 1-2 teaspoons onto each fat bomb.
